Not all car salesmen are sleazy. Most but not all
It really is fun industry to work in because you get to see the whole process from a different perspective.
IME people need to be "managed" into a new car. Cars are expensive and present an on going financial commitment. Is it any wonder people hate buying them?
"All Buyers are liars"... This is actually true because all buyers are worried that by going to a dealership they will inevitably get done.
A good salesman understands this and treats his clients accordingly.
I never used underhanded tactics to sell cars. Mainly because I didn't have to.
That's one of the benefits of working in major dealerships. The cars are generally better and have a known history.
Working in what I would call a "Bomb Yard" is entirely different. There you will well and truly get "jammed" or as we used to say "head mashed".
"Heads", Slang term for customer. It came from looking into a yard and only being able to see the head of the customer as they walk around the yard looking at the cars.
"Burn", Often you manager will tell you to "burn" someone. What it means is that you have a particularly difficult customer who can't make a decision.
"Burning" them means pushing them to buy. They will either buy or never ever come back to your yard.
I did it for 18 months and earned really good money. (better than most doctors)
I left because of the people I working with. Basically a lot of them are crooks or shady.
Even the finance manager used deceptive tactics.
For instance, if a client asked him what interest rate they were being charged he simply wouldn't answer and the app he used to work out the payments didn't show the interest rate.
